This invention relates to a glove turning inachine. i

The chief object of this "invention is to turn gloves more expeditiouslyand automatically by a cyclically operable machine of extremely simplecharacter.

Another object of the invention is to provide a machine which may besupplied with gloves to be turned and after application, which may bemanual, the gloves are automatically turned and then stripped ordischarged from the machine.

In machines of this general type it heretofore has been the practice toprovide an intermittently rotatable element with a plurality of units,each adapted to take a sewed glove at one station, automatically turnthe sewed fingers inside out or to the normal position, depending uponwhether the finger sewing is to be disposed inwardly or outwardly, andthen remove the turned glove.

This practice is also herein adhered to.

The chief feature of the present invention resides in the simplificationof such turning device.

Another feature of the invention resides in the hydraulic or pneumatictype of powerv employed and its'control, the former being utilized withwater, oil or the like and the latter being utilized with compressed airor the like.

Other objects and features of the invention will be set forth more fullyhereinafter.

Fig. 14 is a central sectional view of the power cushioning mechanismtaken on line i'i|4 of Fig. 11 in the direction of the arrows.

In the drawings there is illustrated an embodiment of the inventionselected for exemplification thereof. In Fig. 1, l I indicatesconventional leg structures that at the upper ends are suitably securedto the bed or base plate [2.

The latter at one end is notched out as indicated IE3. Adjacent theretoand at the ends I4 of said plate are the uprights or brackets I5 whichrotatably support a drum structure indicated generally by numeral [6 inFig. 1.

Frojecting radially therefrom are the finger groups, herein four innumber, disposed at degrees. Each group or unit comprises four fingertubes designated generally by the numeral ll. These tubes in drumrotation clear the base l2 by reason of notch it being provided therein.

At the opposite .end of the machine base H supports bracket l8. Bracketsl5 and brackets it have inwardly directed aligned sockets l5a and Ida,see Fig. 2, and disposed therein are the guide and connecting membersI9;

Reference will now be had to the left hand portions of Figs. 1 to 3andFigs. 4 to 10, inclusive. As shown in the first mentioned figures thefinger drum is socketed at 16a to take stems Ila having threadedconnection with tubes 11. Each stem is locked to the drum as at 16b.

In Fig. 4 it will be observed that there is rotatably mounted in thebrackets I5 a shaft 20 and that said shaft projects through the twobrackets. Between the brackets said shaft mounts the drum l6 aforesaid.This drum includes a plate ZI that is provided with four quadrantdisposed openings 22 successively engaged by a locking pin or plunger 23normally constrained to locking position by the spring 24, the springherein being nested in bore 23a of said pin and the pin in turn beingslidably mounted in the bushing 25. The pin is longitudinally slotted asat 26 and disposed in said slot is the spring retainer 27. The lockingpin is only capable of reciprocation toward and away from the drum.

The end of the shaft 20 has secured thereto a member 28 by means of nut28a. The mechanism associated therewith may be enveloped by a detachablecover cap 29 if desired. Note that in Fig. 4 the locking pin is shownretracted. Fig. shows the locking pin projected and disposed in lookingrelation which holds the drum stationary during glove or finger turningoperation hereinafter to be described.

As shown the member 28 is keyed at a to shaft 20. The shaft 20 hasoscillatory movement only. The member 28 pivotally supports at 30 amember 31 which in effect is a cam and lock. Member 28 is cut away at3la to accommodate this cam pawl. Plunger 32 is slidably supported bymember 28 and is constrained by spring 33 to the position shown in Fig.8. In the oscillation of said shaft 20 this pawl is effective uponplunger 23 to retract it and hold it retracted for an appreciableangular movement. reverses, the pawl accordingly is held out of lookingengagement with the drum I6 so that the drum may be indexed a quarterturn at which time the pawl hold out arrangement is slidablydisassociated so that the plunger, under the influence of its spring 24,moves toward the drum and engages in one of the sockets or seats 22'then registering therewith. This holdsthe drum stationary while theglove or finger turning operation is effected.

Reference will now be had more particularly to Figs. 4, 6, 7, 9 and 10wherein the means for oscillating the shaft and the means forintermittently and step-by-step rotating the drum is effected. A cable34, which may be of wire, is wound about a pulley 35 which pulley ismounted on said shaft 20 and clamped thereto at 36. This cableoscillates this pulley. The pulley or power drum is recessed as at 3511forming a chamber wherein there is disposed a ratchet 31 that isrotatably mounted upon the shaft 20 and is rigidly secured as at 38 to asleeve 39 disposed about shaft 20 and is rotatable in the right endbracket [5. A key 40 locks the sleeve 39 to the drum It so that the drummoves with the ratchet and the sleeve 39. The drum as shown at 4| and 42includes bushings that rotatably support it upon the shaft 20. The cabledrum 35 mounts a pawl 43 which herein is shown adapted for radialreciprocation being normally constrained toward the ratchet by thespring 44 retained as at 45, see Figs. 6 and 10.

Fig. 6 shows the parts at the end of the indexing travel of the fingerdrum. Fig. 10 shows the parts in the reverse rotation of shaft 20 andthe ratcheting of the pawl. When the pawl 43 has been rotated, see Fig.10, to the six oclock position, the pawl advances inwardly and engagesthe adjacent tooth face of the ratchet and upon the reverse cabletravel, the ratchet and finger drum are advanced ninety degreeswhereupon the plunger 23 seats in One of the drum sockets 22. Upon themovement of the parts aforesaid corresponding to drum 35 moving fromFig. 6 toward Fig. 10, it will be obvious that the drum l6 and ratchet31 remain stationary. At the proper time the plunger 23 is retracted torelease the flnger drum 16 so that it may be advanced or When the shaft20 4 indexed ninety degrees by ratchet rotation. When the end of thattravel is obtained the plunger 23 is released from its withdrawing forceand again locks the finger drum I6 in indexed position.

Reference will now be had more particularly to Figs. 1 to 3 inclusive.The cable 34, see the right-hand end of the several fingers, is alsomounted upon a pulley 45 carried by the bracket l8. The cable 34 also isprovided with two adjustably mounted stop blocks or abutments 41. Thecable 34 is slidable in a slot or opening 48 in a bracket or arm member49 which is reciprocable toward and away from the drums. When the arm ismoved to the left it leaves the right hand block 41 and travels towardthe left hand block without effecting any cable movement. It then picksup the left hand block and causes the upper run of the cable to movetoward the left and thus causes the drum to rotate in a coun-lterclockwise direction.

When the arm 49 is moved toward the position shown in Fig. 2 itinitially leaves the left hand block 41 and travels toward the righthand block until it engages same. During this interval of arm travel norotation of the cable drum is effected. Thereafter the arm 49 interceptsthe right hand block 41 and moves both blocks and the cable to the rightto the position shown in Figs. 2 and 3. This causes clockwise rotationof the drum 35 and this clockwise rotation of the drum corresponds tothe indexing travel of the finger drum I6. In other words, when the arm49 is moved toward the drums there is effected the ratcheting aforesaid.This ratcheting effects plunger pin withdrawal into the drum and seatingof the pin in the drum and all, obviously, in timed relation to theoperation justdescribed.

Slidably mounted upon guide I9 is the overhead carriage 50 whichincludes cylinder 5!. Disposed in same is a piston (not shown) connectedto rod 52. This carries a stripper mechanism designated generally bynumeral 53. Same also slides on guides 19.

Disposed below the plane of the guides is cylinder 54. A piston (notshown) therein is con nected to rod 55. The two rods are oppositelydirected and the exposed end of rod is connected to arm 56 dependingfrom the carriage 50.

Pressure fluid is alternately supplied to opposite ends of the cylindersand in timed relation. Thus pressure fluid supplied to the right handend of cylinder 54 causes the piston therein, rod 55 and carriage 50 toadvance toward the twb drums. Pressure fluid applied to the right end ofcylinder 5| then projects rod 52 towards the drums.

Pressure fluid supplied to the opposite ends of these cylinders projectsrod 55 and retracts rod 52. The operation is in timed relation andsequential. In place of fluid pressure for one way power application aspring may be employed. Such spring is compressed by fluid pressure inthe initial travel of the piston and upon pressure fluid release, thecompressed spring returns the piston to starting position.

Limit switches are provided to control solenoid operable valves toeifect pressure fluid supply and/or pressure fluid release. These valvesare or may be arranged to waste the cylinder trapped fluid in reversepiston travel. Also each pressure fluid supply and/or waste line mayinclude a manually adjustable valve to regulate the travel speed oftheseveral rods and associated parts.

Herein carriage 50 mounts a transverse sup- 5. port 51 to which isadjustablysecured in spaced relation the members '58 which projecttoward the finger drum I5. These members or .plungers are tapered asshown at 58a and terminate in ball ends 59.

With the finger drum I stationary and a glove disposed upon tubes I! theadvance of balls 59 into the endsof the tubes serves "to draw the glovefingers upon the portions 5.8a while in the tubes until each of the tubeenclosed glove fingers is turned inside out. At this time thestrippermechanism 53 is further advanced and the glove passes throughthe :same. Then the stripper is retracted to remove the glove from thetubes I I. Also the members 58-59 are retracted.

The freed glove then drops from the machine as shown at D in Fig. 1. Aindicates the :glove as ainitially applied to same. B indicates anadvanced position thereof while (1' indicates the finger turningposition.

Since finger drum I6 is only indexed when the upper run of the cable ismoved toward the right in Figs. 1 to 3 it will be obvious that thisaction only occurs when carriage 50 is retracted to the right, see samefigures, by projection of rod 55, the locking 'pin 23 being previouslyretracted from a seat 22 as previously described.

There is provided.astationary'support 6U carrying upwardly extendingmembers GI which are disposed between the 'four fingers for facilitatingglove discharge. The stripper mechanism 53. comprises two opposedmembers 62 with upwardly directed support 63 and these are yieldinglycontracted toward each other by means of a common tension spring 64. Atthe left end of the machine is a travel limit stop and quick actionswitch designated generally by the numeral 65. This switch is providedwith a button 65w which is engageable by actuator 68 carried by thestripper mechanism, when that mechanism is projected to its extremeleft-hand position. Under such circumstances the switch energizes asolenoid control valve. There is also provided a sta tionary switchstructure 66 with button 66w which is engaged by member 69 in the travelof the carriage 50 and stripper 53 and that switch in turn controls thecircuit to a solenoid in turn controlling a valve.

Then there is an additional control 61 having a button 61a that isengaged when the contactor 1!! reaches the extent of its forward travel.There is also a switch 680 having a button 68a engaged by contactor IIwhen the piston rod 55 is fully projected or when the carriage 50 isfully projected to the right.

The sequence of the operation, is as follows: Fluid pressure is appliedto cylinder 54 to advance the carriage 50 to. the left. This moves bothstripper and fingers 58 to the left. When the piston rod 55 issufficiently retracted switch 61 is actuated to supply pressure fluid tothe right end of cylinder 5I. This causes piston rod 52 to be projectedand this projection occurs to the extent determined until the stripper53 (member 68) actuates the switch 65. When this switch is actuated,pressure fluid is reversely applied to cylinder 5| to retract thestripper with respect to cylinder 5|. When this has been effected thecam 59 is arranged to trip a switch, close a circuit controlling thesupply of pressure fluid to the other end of the cylinder 54 to projectits rod 55 and at the same time retract the carriage 50, cylinder 5| andstripper 53. This is continued until the cam II actuates the switch 681)to cut 6. ed the pressure supplyiand reconditionithe application ofpressure to the'other end orthe cylinder 54. whereupon the 'cycle isrepeated.

In this reciprocatory travel of the carriage 50 the arm 49. has been'moved to and 'fro as previously described to efiect in timed relationthe unlocking of the finger drum I6 and the indexing thereof occurs, towit. station to station, step by step rotation as previously described.

IniFigs. ll to '14 there is illustrated a modified form of theinvention, :same relating more particularly to the. finger *drumpowerand indexing mechanism. Herein generally numerals of the onehundredseries designateparts like or similar to those previously described anddesignated by numerals of the primary-series.

For-example in Fig. 11,*II6 indicates the finger drum rotatably mountedon shaft I20. Herein shaft I 20 mounts arm 1'35 pivotally connected atI35a to link 134a pivotally connected at I341: to actuating rod I34. Theexposed end of sleeve I319 herein may include the internal pawl andratchet connection but herein same is unnecessary. In the sleeve pockets139b, closed by the retainers I3.9a,3there is the headed pin I13normally constrained outwardly "by spring I44. Key I45 prevents pinrotation. The exposed end of pinv M3 is beveled as 'at I31.

There areas many pins as there are stations for the, drum. In linkadvance to the left, see Fig. 12. the arm I35 rotates counter clockwise,see Fig. 11, and engages face I31 of the uppermost pm 143 and forcessame inwardly until the arm has, passed the pin whereupon the pin, dueto spring 1M4, pops out. Upon reverse rotation of arm 135. same engagesthat pin and picks it up and the drum H6 for drum indexing.

Note that the-drumkis held stationary as before during thecounterclockwise rotation of the arm, and in the clockwise rotationthereof the drum lock is initially released and held released until thedrum has been indexed whereupon the drum lock is reestablished, all aspreviously describe and incident to oscillation of shaft I20.

The means for reciprocating rod I34 includes arm or bracket F49 carriedby the upper carriage slidable on guides I ID. This bracket, see Fig.14, has a hole I48. The rod I 34 slides through this hole. The rod maybe suitably supported in. guide brackets as shown. The rod carries stopsl4! which are threaded upon the rod and locked by nut I 41a.

Thus the rod I34 is alternately picked by arm 4 and reciprocated. Asbefore there is a dwell period determined by the spacing between stopsI41. To cushion the index stroke and rod pickup there is provided, seeFig. 14, a sleeve 148a inhole I48. Sleeve I 48b is hardened and iscarried by sleeve I 48aand is rigid with cushion spring I480.

The operation. of this form of the invention is substantially thatpreviously described except rod I34 is substituted for cable 34 and theimmediate associated parts are modified as illustrated and lastdescribed.
